Myc has also been recently recognized as an important regulator of "stemness" as it is able both to activate an embryonic stem cell-like transcriptional module and, when ectopically expressed, to increase the cancer stem cell fraction and enhance tumorigenicity

Of the 220 genes that [24] identified as a core set of "stemness" genes common to multiple types of stem cells but not found in differentiated cells, 26. 8% (60/220) are expressed by Bergmann glia at P6 (
